Now, let's look at the types of systems. Exhaust-only. All right, let's get this one out of the way first. Using exhaust fans is great for local ventilation of bathrooms, kitchens, garages, and sub-slab areas (for radon control), but it's not a great strategy for whole-house ventilation.

When writing Common Sense, Paine wanted to show the common man why the United States should be independent of England. He also wanted to show these people that they had the resources needed to build a navy.
In Common Sense, Thomas Paine argues for American independence. His argument begins with more general, theoretical reflections about government and religion, then progresses onto the specifics of the colonial situation. Paine begins by distinguishing between government and society. Society, according to Paine, is everything constructive and good that people join together to accomplish. Government, on the other hand, is an institution whose sole purpose is to protect us from our own vices. Government has its origins in the evil of man and is therefore a necessary evil at best.
